I just recently moved to Japan from the Seattle area and brought a couple treasured items along to create with, the Mono/Poly being one of them. So today, I was recording with the MonoPoly playing in poly mode while adjusting the filter and the sound very quickly faded out. No nothing from any of the oscillators the filter or the noise gen. I can however hear a very quiet sound of maybe the ADSR when I play the keys. Just so all possible information is present I want to also note that I was powering it through a newly purchased step up transformer (not sure if that could have had any effect on my precious)


I also have a couple keys that don't work -it's not just dirty contacts either. It looks like the contacts for those keys are corroded somehow. Is it possible to find or repair the contact board

Please, any help would be greatly appreciated!

thank you,
chad
